J/A+A/458/767       Vilnius photometry on M92                (Smriglio+, 2006)

Photometric determination of the [Fe/H] ratio for the globular cluster M92. Smriglio F., Dasgupta A.K., Boyle R.P. <Astron. Astrophys., 458, 767-775 (2006)> =2006A&A...458..767S
ADC_Keywords: Clusters, globular ; Photometry, Vilnius Keywords: stars: fundamental parameters - stars: general - Galaxy: globular clusters: individual: M 92 Abstract: CCD observations of the northern globular cluster M 92 were obtained in the PXYVS colors of the Vilnius photometric system. The results for 230 stars in an area centered on the cluster and for 178 stars in an area west of the cluster down to V=17.0mag are presented. After a brief outline of the data pathway from observations to reduction via IRAF and a discussion of the photometric errors, the [Fe/H] ratio of the globular cluster M 92 is determined by multicolor PXYVS Vilnius photometry. Description: The observations were obtained using five Vilnius filters (P, X, Y, V, S), during two different observing runs in six nights in May and July 1996 with the 150 cm telescope of Bologna University situated at an altitude of about 3000 feet in Loiano (Northern Italy Apennines).
